Yellow Orange light seen in sky in South Burlington.At about 7:50 pm (19:50) on Firday April 10th me and my girlfriend were heading back from University Mall in south Burlington. We had just gotten on interstate I89 South via Exit 14-E, it was dark enough were everyone had their headlights on, but not quite enogh to see stars yet. The treeline was black but the ski was a deep blue. About 5 minutes after we merger to the interstate I saw a yellowish light low in the sky at to the left of me at about 10 o'clock. At first I thought it was Jupiter because it was so vividly bright compared to the rest of the sky, and it looked like the first start out. After looking at it for a second more, I realized it was too orangey yellowish and too bright, and almost seemed to be getting brighter. After about 30 seconds I can see its perspective changes making it seem like it is much closer than a star, and seems alsmost fixed in the sky over the ridge line maybe three miles away, andaune about 5,000 feet up. At this point I wake my girlfriend up in the passenger seat and say "babe what's that?". She looks at it for a second and says "A light on a tower like an airport?" but it was not blinking or flickering, was very yellow and Orange, not red like an airport. Also there was only one light and it was so bright there was a little halo of yellow in the clouds around it so you could see there was no tower below it, and there is no airport south of Burlington. After about abother minute of watching it, it is directly left of us, 9 o'clock, and it just sort of zooms away from us. It appeared to move due east at extreme speed. Seemingly no acceleraton period,'an disappearing over the horizon as quick as you could snap your fingers. I would guess less than 0.1 seconds. That was the last of anything strange I saw on my 2 hour drive south that night. I was watching the sky carefully cause I was so unsettled from what I saw.Me and my girlfriend are both 17 year old highs highschoolers who were in Burlington for the day. Neither of us drink, do drugs, smoke or take any medication. We both felt fine all day and when we saw it, other than my girlfriend just woke up. I have an intrest in UFOs because they raise compelling questions and involve ideas I am interested in, but I have no real knowledge other than a few things on the internet, and convorsations with my Physics and Chem teachers. The only thing I could think of that would be helpful would be that the light was the same exact color as old High Pressire Sodium street lamps.If you know or think of anything that could be helpful or interesting, please contact me.
